Title: Heat-sensitive recorder
Inventor: NISHIYAMA RYUJI
IPC: B41J2/38
Filed: 1988-05-23
Abstract: PURPOSE:To prevent generation of shortening of the life-time and sticking of a heating element and so on, by judging whether respective surrounding dots around a printed dot are printed or not, and by heat-controlling the heating element corresponding to non-printed dots in such manner that said heating element is kept warm and heated within a temperature range where no ink is transferred to a recording medium. CONSTITUTION:When there are printed data of dots to be printed 2, 3 and non-printed dots 1, 4, 5, 6, 7, 8, 9, a heating element corresponding to dots 1, 5, 6, 8, 9 being originally no printed data is kept warm and heated at a temperature within a range where no ink is transferred to a recording medium. Said dots to be printed 2, 3 is given an applied energy usually necessary for printing. Thus, unnecessary heat dissipation from a necessary printed dot heating element is decreased so that an excessive energy is not required to be supplied and neither shortening of the life-time nor sticking of said heating element are generated. Also, a single dot and vertical and horizontal one-dot lines can be printed with a high accuracy.

IPC: G11B9/06
Filed: 1979-09-29
Abstract: PURPOSE:To obtain reproduced picture and reproduced sounds of high quality by separately recording video and sound signal information on a recording disk and by recording synchronizing signal information for every signal information. CONSTITUTION:On one side 12 of recording disk 11, video signal information is recorded along the spirally set recording line and on the other surface 13, sound signal information is separately recorded. As pieces of synchronizing signal information for synchronization between reproduced signals of both pieces of signal information, address signals XA and XB are inserted into both pieces of signal information at proper separate positions in vertical blanking period VBL by being binary-coded. Then, the reproducing device side reads both sides simultaneously and decides address signals XA and XB to synchronize both reproduced signals of both pieces of signal informations, so that both pieces of signal information will never interfere mutually in signal reproduction.

Filed: 1990-05-17
Abstract: PURPOSE: To allow growth of nuclear fuel rods sue to thermal expansion and improve burnup by constituting upper tieplate and lower tieplate as to be capable of accessing and separating within a side wall enclosure. CONSTITUTION: If the downward supporting contact force of an upper core support plate pressing on an upper plate 30 of upper nozzle assembly 12 is removed, an upper structure 24 is separated from a lower adapter plate 26 by a coil spring 60 and becomes an expanded state. At this moment, the seating structure 56 of the plate 26 and the holding structure 44 of a side wall enclosure 32 couple to hold the plate 26 within the enclosure 32. By this, the interval between both plates 26 and 30 becomes maximum and a sufficient space to insert the structure elements of fuel assembly treatment device in the hole of the plate 30 is created.  Then, by adding downward support contact force to the plate 30 to push the spring 60 and sliding the enclosure 32 downward against the plate 26, the assembly 12 can be made compressed state and the distance between the plate 26 and fuel rod 18 upper end becomes large and therefore, the growth of fuel rods 18 can be allowed.

Abstract: PURPOSE:To cause a tape traveling switching mechanism to be compact and simple and to reduce a noise by executing the exchange of a reel shaft with the operation of a same driving and revolving body and a turning member and switching the contact and separation of a pinch roller and a capstan shaft. CONSTITUTION:When a driving and revolving body 4 is inverted in a clock-wise direction with being inverted to a motor, a turning member 7 is also turned in the clock- wise direction and an intermediate gear 8 is separated from an operating gear 3A of a reel shaft 1A. Continuously, a pin 10 of an intermittent gear 9 is pressed in a counter-clock-wise direction by the turning force of the turning member 7 and the gear 9 is revolved in the counter-clock-wise direction and engaged with a large diameter gear 5. The intermittent gear 9 to be engaged with the large diameter gear 5 is revolved in the counter-clock-wise direction by the revolving force of the driving and revolving body 4 and a pitch roller switch member 12, which is engaged to the pin 10, is moved in a right direction. As a result, an inclining surface 12B in the left side of the pinch roller switching member 12 is separated from a pinch arm 14B and a pinch roller 13B is contacted to a capstan shaft 2B by pressure. Thus, the number of parts is decreased and the mechanism can be made compact. Then, the noise can be reduced.

Title: Variable delay circuit
Inventor: HANAOKA TETSUO
IPC: H03H7/30
Filed: 1977-10-19
Abstract: PURPOSE:To secure the flat frequency characteristics at all times up to the frequency band which is required to the signal to be delayed, by varying the high-band compensation quantity in accordnce with the fequency band of the delay line. CONSTITUTION:In the variable delay circuit, the control signal generatd through control signal generator circuit 403 is applied to variable capacity diode DV of variable delay line 402 to vary both the delay time and frequency band. High-band compensating variable capacity diode 409 and 410 are connected in parallel and with opposite polarity to each other at the emitter side of emitter earthed amplifier 405 via capacitor 407, and the plus and minus control signals featuring inversed polarities to each other are applied to the other ends of diode 409 and 410 from circuit 403. When the absolute value of the control signal decreases, DV increases with f0 narrowed. At the same time, the capacity of diode 409 and 410 increases to give compensation to the high band. In case the absolute value of the control signal increases, f0 is increased. Accordingly, the high band is not compensated so much.

Filed: 1981-08-12
Abstract: PURPOSE:To determine the time upto the arrival of an object approaching at a constant speed with a simple construction by measuring the variation rate in the level of receiving radio waves emitted from a moving object. CONSTITUTION:A wide dynamic receiving circuit 1 receives and transmits radio waves emitted from a moving object to a memory circuit 3 via an analog-digital convertion circuit 2. At the same time, a timing signal is sent to the circuit 3 from a timing circuit 4 to memorize a receiving level and then, a certain time later, a timing signal is sent to a level variation rate computing circuit 50 to fetch the current signal level. The signal level memorized in the circuit 3 is read out to determine the corresponding DELTAPdB. This DELTAPdB precisely corresponds to the time up to the arrival of the moving object and thus, the time up to the arrival thereof is calculated by a specified computation with a time calculation circuit 6.

Title: Color registration correcting method for image forming device
Inventor: KIM NAM-RYOUNG
IPC: B41J2/525
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To provide a color registration correcting method for an image forming device capable of accurately adjusting the color registration in a subscanning direction. SOLUTION: An optional LSU(laser scanning unit) is selected out of Y, M, C and K LSUs and the optional one is independently driven. A synchronism/ window signal deviated as much as the misregistration between the LSUs is separately generated for the remaining LSUs other than the selected LSU. Respective driving motors are driven so that the remaining LSUs may cope with the synchronism/window signal. Thus, the optional reference LSU is independently driven and the deviation distance between the LSU and the remaining LSUs are separately obtained, and the synchronism/window signal is generated based on the obtained distance so that each LSU may cope with the signal, so that the error in loading the LSU in the asynchronous subscanning direction of the LSU is easily corrected.

The transmitted infrared laser beam is reflected by a rotating polygon mirror 20 and passes a lens 21 and a mirror 19 and is thrown to a recording medium 25. During this time, the rotating polygon mirror 20 is rotated at a uniform speed to scan the laser beam on the recording medium 25 in one direction. Since the recording medium 25 is moved at a uniform speed in the direction perpendicular to the scanning direction of the laser beam, the laser beam is scanned throughout the surface of the recording medium 25 as the result.
